    Raspberry Pi    Adafruit GPS
    5V              Vin
    GND             GND
                    EN

    GPIO25          RST

    Example of how to use it:

    At the same time, on the sender
    >>> my_frm95 = RFM95()
    >>> my_rfm95.send("Hello world!")

    At the same time, on the receiver :
    >>> my_rfm95 = RFM95()
    >>> my_rfm95.receive()
    Hello world!
